I have a Fiat Chausson 628eb 17 plate and the leisure batteries aren't holding chargeand I need to replace. I have followed the forum advice and removed bolts and the yellow Anderson plug has been unclipped. I am left with one black wire (air bag?) that is stopping me detach the seat. The wire goes from below the battery through the swivel seat and then goes up into the seat. It appears to go behind the plastic panel at the bottom of the seat which I cannot access as the seat adjustment furled knob stops my taking it off. I am hoping a Funster has overcome this issue and can advise. Its frustrating as I cant get the new batteries in until I sort this issue. Thanking you in advance Andrew
